Thanks for the update, @BobInNH!
Sorry to hear about the issue. We suggest you run a quick update on your Roku to see channel update, go to Settings > System > System update > Check now. Restart your Roku and try again. If it did not help, it appears that the issue may be isolated to the channel in question. This suggests that there may be a problem with the channel itself that requires attention from the channel publisher. Please note that channels on Roku are developed and managed by individual channel publishers.
To resolve the issue, it is recommended that you contact the support team of Youtuve TV directly and provide them with your feedback. You can reach them here: YouTube TV Support.
I'm going to mark this post as solved as we've come to the end of our troubleshooting options but I hope the information above is helpful, and please follow up here if you find any other solution so that others could benefit.
